NASA's Commercial Crew Program astronauts, wearing spacesuits and augmented reality headsets, rehearse returning to Earth from the International Space Station during recent testing at Boeing's Extended Reality Laboratory in Philadelphia. The astronauts are seated upside down so they can practice releasing their seat harness and moving to the side hatch of the Starliner without assistance. The astronauts wearing the mixed reality gear see a digital version of the interior of the Starliner as it would look in the real-life scenario while interacting with the environment around them.

NASA, Boeing and United Launch Alliance (ULA) conduct a simulation of launch procedures for Boeing’s Orbital Test Flight, the first uncrewed test of the company’s CST-100 Starliner and a ULA Atlas V rocket. Launch teams participated in the simulation across the country, including inside the Launch Vehicle Data Center at Hangar AE at Cape Canaveral Air Force Station in Florida. The Starliner will launch on an Atlas V rocket to the International Space Station as part of NASA’s Commercial Crew Program.
